A
Create an AWS Storage Gateway file gateway. Create a file share that uses the required client protocol. Connect the application server to the file share.
B
Create an Amazon EC2 Windows instance. Install and configure a Windows file share role on the instance. Connect the application server to the file share.
C
Create an Amazon Elastic File System (Amazon EFS) file system, and configure it to support Lustre. Attach the file system to the origin server. Connect the application server to the file system.
D
Create an Amazon FSx for Lustre file system. Attach the file system to the origin server. Connect the application server to the file system.
Explanation:
Explanation
Correct Answer: D - Create an Amazon FSx for Lustre file system. Attach the file system to the origin server. Connect the application server to the file system.
Why this is correct:
-
Amazon FSx for Lustre is specifically designed for high-performance computing workloads that require the Lustre file system. It provides a fully managed Lustre file system service.
-
Fully managed requirement: Amazon FSx for Lustre is a fully managed service that handles all the administrative tasks like hardware provisioning, software configuration, patching, and backups.
-
Lustre client compatibility: FSx for Lustre supports standard Lustre clients, allowing on-premises applications to access the file system using the Lustre protocol.
-
On-premises connectivity: The solution can be accessed from on-premises data centers using AWS Direct Connect or VPN connections.
Why other options are incorrect:
-
Option A (Storage Gateway): While Storage Gateway provides hybrid storage solutions, it doesn't support the Lustre protocol. It supports NFS, SMB, and iSCSI protocols, but not Lustre.
-
Option B (EC2 Windows instance): This is not a fully managed solution (requires manual installation and configuration), and Windows file shares don't support the Lustre protocol.
-
Option C (Amazon EFS): Amazon EFS doesn't support the Lustre protocol. EFS is based on NFSv4 protocol, and while it can be configured for performance, it doesn't provide Lustre compatibility.
Key AWS Services Mentioned:
- Amazon FSx for Lustre: Fully managed Lustre file system service
- Amazon EFS: Fully managed NFS file system service
- AWS Storage Gateway: Hybrid storage service for connecting on-premises environments to AWS storage
- Amazon EC2: Virtual servers in the cloud
This question tests knowledge of AWS storage services and their specific use cases, particularly for high-performance computing workloads requiring Lustre file system access.
